Tips & Tricks:

To work as you wish you have to make the right choice for the operator of filter field, most likely to use "Contains"

For referenced entities (entity reference, node references, term reference) use referenced entity fields for the filters with the right relationships.

*** If you have more titles fields defined in fields and/or filters the correspondence between field & filter must be right
for example: if field is title_2 then also the filter field should be title_2
